I was diagnosed with GCA May 19 th, 2016. Since then, I've been on megadoses of prednisone, starting at 60 mgs.a day, then 50, 40, and tomorrow starts 30 mgs. Over 3000+ mgs. in three months. One minute rage, the next restlessness and exhaustion. Will the tapering this time help, or is this endless til the GCA is considered cured?
